As global manufacturing accelerates towards high-end and intelligent production, non-ferrous metals—key industrial materials—face increasingly stringent requirements for core parameters such as crystallization temperature, electrical conductivity, and thermal conductivity. In the fields of new energy storage and advanced metallurgy, precision in molten salt conductivity measurements must be controlled within ±0.5%, while crystallization temperature deviations should be kept below 2°C. These stringent standards push the boundaries
of material performance and impose unprecedented accuracy demands on high-temperature molten material property testing equipment.
Aluminum Electrolysis Process: Enhanced crystallization temperature accuracy reduces energy consumption per ton of aluminum by 3% ("Light Metals," 2024 Research Report).
Molten Salt Thermal Storage for CSP: U.S.-based SolarReserve mandates molten salt (60% NaNO₃ + 40% KNO₃) conductivity measurement repeatability error below 0.3% (IEEE 1175-2023 Standard).
However, traditional metallurgical production remains largely experience-driven, with existing testing methods struggling to accurately characterize the critical physical properties of molten salts and melts. This limitation hampers process optimization and product quality improvement.
